CARL HOCHSTADT, OF CHICAGO, ILLINOIS, ASSIGNOR TO MAR-DER, LUSE & 00.,OF SAME PLACE.

TYPE-CASTING MOLD.

SPECIFICATION forming part of Letters Patent No. 336,483, dated February16, 1886.

Application filed July 13, 1885. Serial No. 171.411.

1'0 all whom it may concern.-

Be it known that I, CARL HOOHSTADT, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in TypeCasting Molds, of which the .following is a specification, referencebeing had therein to the accompanying drawings.

The object of my invention is to facilitate the casting of types with agroove or recess,in which smaller type may be placed, by firmly securinga core within a type-casting mold and furnishing said core with amovable rod passing through its center, for the purpose of quicklyseparating the grooved type from the core and mold.

In the accompanying drawings, Figure 1 is a front view of a type-castingmold embodying my invention. Fig. 2 is a horizontal section on line asroof Fig. 1. Fig. 8is a perspective View of one of the types produced.Fig. 4 is a vertical section through the core and type, showing thedischarge of type from the mold. Fig. 5 is a View of a portion of thelower half of a type-casting mold. Fig. 6 illustrates the use of saidtype.

The parts A A A", and other parts not herein specifically described, ofmy type-casting mold are of the usual construction.

B designates a core firmly held in the mold by screws, as shown in Figs.4 and 5.

C designates a cylindrical opening through the longitudinal center ofthe core, to receive the movable rod D, extending entirely through thecore. The outer end,b,ofthe movable rod is pivoted to a lever, E, theend a of which is pivoted to an arm, d, which is pivoted to the (Nomodel.)

part A of the mold. The removable rod is provided with a collar, f,having a threaded hole to receive the set-screw F, to secure the rod inplace, so that it may not be withdrawn entirely from the matrix-space,t0prevent the formation of a projection on the side of the type G incasting it.

In the operation of molding the type, the metal being run into thematrixspace and allowed to cool, the mold is opened, and by means of thelever the rod is projected beyond the face of the core against the type,separating it from the mold, as shown in Fig. 4. The rod is thenwithdrawn and secured in place by the set-screw with the inner end flushwith the face of the core, the mold is closed, and the operation ofmolding and removingthe type c0ntinued,as above described.

What I claim as new,'and desire to secure by Letters Patent, is-

1. In a mold for casting grooved type, a perforated core firmly fixed inthe mold, in combination with a movable rod attached to the mold andadapted to separate the type from the core, substantially as and for thepurpose described.

2. In a type-casting mold,the core B,having a longitudinal opening, C,in combination with the movable rod D,extended through the core, and thelever E, pivoted to the mold and the rod, substantially as and for thepurposes described.

In testimony whereof I have affixed my sig nature in presence of twoWitnesses;

CARL HOCHSTADT.
